I know it's ideal to match the hatch but generally speaking what types of dry's and nymphs (sizes too) would you suggest to use for the most success this time of year and going into the fall? I'll be mostly fishing in fertile streams in southeastern and south central PA if that helps. Thanks for all your help!

Blue wing olives in sizes 16-24. Dries, emergers and nymphs. PT nymphs are a good imitation. That's my best suggestion and favorite fall hatch. EDIT: excuse my first post, I thought you were asking for summer suggestions, not fall.

Thanks for all the feedback. The only real success that I have had lately has been with streamers. Black flash back PT nymphs were hot for about a day for me. I haven't gotten a rise out of a caddis or a stimi for a while now, and have seen any fish rising period.

This is good advice!

Trout fishing in the late summer and fall months, esp Sept and October, can be rather difficult Hopback. Many streams remain fairly warm, low and clear, and often don't have as many fish as springtime and early summer (the stocked streams will see heavy attrition of stocked fish in the spring and summer). Generally, I tend to use pretty small nymphs and dry flies in the fall. Fertile streams in SEPA will likely enhance this - I'd stick with nymphs and dries in the smaller sizes - say #16 down to #20. This is pretty small. The actual patterns aren't too important. In addition to beetles, some basic dry flies like Adams or Griffith's Gnat will work well. Later in October and November, higher water levels and spawning season will usually put trout in a more aggressive mood and streamers will continue to fish well and you can go with bigger nymphs in the #14 up to #12 range.

Iso's, BWO's maybe some caddis. I've been on the lehigh in the gorge 3 times in the past 2 weeks and the first time they were keyed in on the stoneflies(yellow) and the last two times it was all about the iso's. I had pretty good luck with parachutes and rusty spinners but I had to lighten up my patterns some. Duns are like a light brown with tan tails and the spinners are more like a rust color or burnt orange almost.
